The database is constructed for understanding characteristics of ground motion with pulse-like velocity and providing time history as input motions for both shaking table test and numerical simulations of structural dynamics. This database consists of 198 three-component ground motion records with pulse-like velocities in Taiwan from 22 events, and 112 two- or three-component ground motion records in other regions from 32 events.
The records were processed using two different approaches, please refer to the technical reports (Kuo et al. 2019) of the database for detail before you use it. Identification of velocity pulse is based on the approach proposed by Shahi and Baker (2014). This database provides time history of accelerations, velocities, and displacements, as well as the spectral acceleration.
